Stability analysis for a petrochemical complex with on-site generation tied to the Mexican utility grid

Electrical systems of industrial plants, i.e. oil, gas, and petrochemical industries usually incorporate local generation either to supply the complete demand of the industrial plant or to ensure continuity in electrical supply to critical processes when interconnected with the utility grid. Disturbances such as electrical short-circuits either in the distribution system of the industrial facility or in the utility grid, loss of local generation or system islanding condition may compromise the continuity of critical processes in the industrial plant or even cause the blackout of the industrial facility. In this paper, the impact of losing local generation and the industrial-utility tie on the dynamics of the electrical system of a petrochemical facility is addressed.
